Referring to the drawings by numerals, a complete window casing mold 10is shown as assembled in a wall opening 11, formed in a composite wall12.

The structure of the composite wall 12 is best illustrated in Fig. 8 andhas facings 13 and 14 which are built up, as shown, from slabs 15. Eachslab 15 has tongues 16 provided upon the upper and lower longitudinaledges 18 thereof near the ends of the slab. Apertures 19 are formed inthe central portions of the slab edges 18 so that when the slabs 15 areerected edge to edge in breakjointrelation to form the facings 13 and14, as shown in Fig. 8, the tongues 16 of each adjacent pair of slabs ina given horizontal course will project upwardly and downwardly intoapertures 19 of the central portions of slabs of the Courses immediatelyabove and below. j Inasmuch as each slab 15 is thus joined at siXseparate points with slabs thereabove and therebelow, al1 of the slabs15 used in the erection of the facings 13 and 14 assume a true alignmentwith eachother in which the inter-facial planes of eachslab, upon whichboth the tongues 16 and the apertures 19 are formed, substantiallycoincide.

The facings 13 and 14 are held together by tie members 25. Each of thetie members 25 has a connecting element 26 and a pair of end plates 27which are adapted to be secured to the opposite ends thereof. Eachconnecting element 26 is preferably made of wire and has a centralportion 28 which terminates in arcuate bends 29 which return to formshort portions 30 which are aligned with the centralportion 28 and whichare bent vertically downward at their outer ends to form necks V31, fromthe lower ends of which the ends 32 of the element 26 are bent inopposite directions perpendicularly relative tothe central portion 28 ofthe element 26.

Each end plate 27 has a central body portion 35 which is provided withcorrugations 36, and which has pairs of-ears 37 eX- tending outwardtherefrom in opposite directions to form slots 38, as clearly shown inFig. 10. The body 35 of each end plate 27 extends inward to form atongue 40 which has a hole 41 which is adapted to receive the ends 32 ofthe connecting element 26.

Inv the erection of the wall 12, tie members 25 are laid acrossthe wallas each pair of opposite courses of slabs in the facings 13 and 14 iscompletely set up. The tie members 25 'are thus laid so that the endplates 27 rest in a position clearly shown in Fig. 8, one of the endplates27' of each tie member 25 receiving, through the slots 38, theupward projecting tongues 16 from adjoining slabs 15 in one of thefacings 13 or 14. The other end plate 27 rests upon a slab of theopposite facing and lies over an aperture 19 so that the slots 38 aredisposed directly over this aperture. With the erection of the next,

higher courses of slabs 0f the facings 13 and 14, apertures 19 of thesenext courses will fit down over the tongues 16 which project upwardlythrough the slots 38 and thus hold certain end plates 27 disposed aboutthese tongues and securely positioned between vertically adjacentcourses of slabs. Likewise, the tongues 16 projecting downward from thenext course ofslabs will pass through slots 38 disposed about apertures19, as clearly shown in Fig. 9. The tongues 16 are connected to eachother through the interior of the slab 15 by reinforcing wires 45 from,which the tongues 16 are formed by bending.

The tie members 25 are alternately Vreversed in position so that therecesses 46 formed by the arcuate bends 29 in the connecting elements 26of each vertical series of tie members 25, will form guideways whichsecurely retain in place vertical reinforcing rods 47 when these areinterwoven between theV tie members 25 at the points of the formation ofthe arcuate bends 29.

At the commencing of the erection of the wall 12, the facings 13 and 14are built up to a height'of four or five slabs,as shown, and heldvertically plumb by a limited amount of scaffolding, showndiagrammatically at 47a in Fig. 8. Airspace forms 48 are then placeddownwardly in the space 49 formed between the facings 13 and 14 so thatone of the forms 48k is disposed between each adjacent pair of verticalseries of tie members 25 in thesame manner as the single form 48 isshown between onepair of these series in Fig. 8. The other forms 48 usedin the construction of the wall 12 were left out of Fig. 8 in order thatcertain details of this View might not be covered up. `When the forms 48have all been properly positioned between the facings 13 and 14, plasticconcrete is poured into the space 49 about the forms 48 to form amonolithic concrete core for the wall 12.

When the wall 12 is thus formed webs 52 may be permitted to form betweenadjacent `edges of the forms 48 which will connect the opposite facings13 and 14 and transmit moisture, heat or cold therebetween. It isthere-A fore planned to use strips 53 of insulating material 'havingslits 54 formed therein so that the strips 53 can be fitted over theconnecting elements 26 of each vertical series of tie members 25 and thestrips 53 extend across the entire width of the webs 52 at the centralportion thereof and completely insulate opposite facings 13 and 14 ofthe wall 12.

In order to strengthen the wall 12, keys 55 are disposed in suitableholes 56 formed inv the strips 53 so that opposite ends of thekcys 55will be cast into opposite portions of the divided web 52 to give thewall 12 an essential unitj7 even though it is .practically divided inthe middle by air spaces and strips of insulation 53. Further details ofthe com# positel wall 12 will be found in my co-pendin g applicationreferred to above.

lVhen, in the course of the construction of the composite wall 12, itbecomes desirable to form a casing for a wall opening therein, this willpreferably be cast at the same time as the interior 49 of the wallitself in a manner which may be described as follows:

The opposite facings 13 and 14 are here shown built up to completelyenclose the wall opening 11. V

The. mold 10, as shown in Fig. 1', about the opening 11 may be formed inseveral different ways but it is particularly desirable that it beassembled as a unit for convenience in handling, and it is alsodesirable that the mold be easily disassembled after the wall and casinghave been cast so that no evidence of the mold is left upon thecompleted wall and casing. n a casing 65, such as shown in Figs. 2, 3and 4, it is very desirable to have a window-hanging frame 66 extendentirely around the interior edge of the opening 67 of the casing. Inthe present invention a Windowhanging frame 66 of steel Z-barconstruction is shown which it is the purpose of this invention to castdirectly into the opening 67 of the casing when the wall 12 and thecasing 65 are simultaneously poured.

Referring to Fig. 12 the above purposes are accomplished by theprovision of a central telescopic mold member 70, andV inside andoutside mold members 71 and 72 respectively. The right hand halves 73,74 and 75 of the mold members 7 0, 71 and 72 respectively are shown inFig. 12. Each of these halves consists of upper and lower elements. rlhehalf 73 of the mold member 70 has an upper element 76 and a lowerelement 77. The element 76 has a head portion 7 7a and a jamb portion78. rlhe element 77 has a jamb portion 79 and a sill portion 80.

The half-7 4 of the mold member 71 has upper and lower elements 81'and82. The element 81 has a head portion 84 and a jamb portion 85. Thelower element 82 has a jamb portion 86 and a sill portion 87. The half75 of the mold member 72 has upper and lower elements 90 an-d 91respectively. The element 90 has a head portion 92 and a jamb portion93, while the element 91 has a j amb portion 94 and a sill portion 95.The two portions of each of the above-mentioned elements are connectedtogether at right angles to each other. rl`he jamb portions of the upperand lower elements of each of the mold member halves 7 3` 74 and 75 aretelescoped together, as clearly shown in Fig. 12. This telescoping isfor the purpose of permitting a vertical eX- tension of the mold 10 tolit a Wall opening 11 varying in its vertical dimension.

In assembling the mold 10, the central mold member is telescopicallyextended so that the upper and lower elements ofthe half 73 thereof litinto the Lipper and lower right hand corners of the Window-hanging frame66, here shown fragmentarily for the purpose of illustration. When thehalf 73 of the mold member 70 is thus positioned within one side y ofthe window-hanging frame 66, the upper and lower elements of each of thehalves 74 and of the mold members 71 and 72 are telescoped together soas to correspond in vertical dimension with the half 73 of the moldmember 70, and are then shifted inward so that an interior surface ofeach of the mold member halves 74 and 75 fit upon corresponding edgesurfaces of the half 73 of the inner mold member 70. When one-half ofthe mold 10 is thus assembled, the opposite complementary halves of themold members 7 0, 71 and 72 are assembled in an identical manner uponthe window-hanging frame 66. When the opposite halves are thus assembledthey will not only be telescoped so as to correspond in verticaldimension to the window-hanging frame 66, but their head portions andsill portions will telescopically meet and combine with the head andsill portions of the mold members 7 0, 71 and 72 to form complete headand sill-forming cavities which unite at their opposite ends with thetops and bottoms of jamb-forming cavities, the right hand one of whichis formed by the mold members shown in Fig. 12. Thus, within certainlimits the members 70, 71 and 72 of the mold 10 telescopically unite toform acomplete molding cavity 'for forming a casing about thewindow-hanging frame 66 so that the casing formed thereby will conformto the size of the window-hanging frame.

Means are provided for unitingv the members 70, 71 and 72 upon thelframe 66, when they are thus positioned, to` form the assembled mold10. This means comprises a temporary bracing structure 100 which haslside members 101, a top member 102, abottom member 103, and verticalspacers 104. The

side members 101. as clearly shown in Fig. 5,

are formed of planks 106 uponwhich wooden strips 107,108, 109, and 110are nailed. rlhe strips 107 to 110 inclusive are of such shape and sizethat they fit into the inequalities of the jamb portions ofthe mold 10so as to 'hold members 7 0, 71 and 72 -in the spaced relation in whichthey are shown in Fig. 5. The top member 102 of thebracing structure 100also comprisesV a plank 106 which has blocks 107 to 110 inclusivevformedthereonV in identically the same manner as in the side members 101. Thelower member 103 of the bracing structure 100 has azplank 113 which isprovided with blocks 114, 115, 116. and 117 which lfit over contiguousedges of the sill-V in'such position that when it islowered directlydownward upon this sill portion of the mold it will correctly secure thevarious ele,- ments of the mold rigi-dly together in the desiredposition.

As will be noted in this figure, flanges 120, formed upon the sillportions 95 of the mold elements 91, are designed to be received in anarrow slot 121 provided between the wooden strips 116 and 117 of thebracing vmember 103. Moreover, the channel-like bent portion 122 of thesill portions 80 of the mol-d elements 77 fit snugly over the lower barof the windowhanging frame 66 so that when this channe-l portion 122 isreceived into an opening 125 provided between the strips 115 and 116,the mold element sill portions 80 will be held in spaced relationrelative tothe sill portions 95 of the outer mold ,member 72.

An opening 126 between the strips 114 and 115 of the bracing member 103also receives a short vertical flange 128 provided along the inner,upper edge of the sill portions 87 of the inner mold member 71 so as tohold the sill portion 87 in spaced relation to the sill portion 80 andthus, also, to the sill portion `95. The flanges 120 and 128 and thechannel-shaped formation 122 are formed vupon all of the elements of thecorresponding mold members 70, 71 and 72 so that these flangesextend'continuously around the inner edge of the opening within; themold 10 and are also engaged, as shown clearly in Fig. 5, by the woodenblocks 107 and 110, inclusive, which are provided upon the side andupper bracing members V101 and 102.

Vhen the mold 10 1s assembled upon the window-hanging frame 66 for theformation of a easement in a wall opening 11, the character of thebracing members 101, 102 and 103 will depend upon the width of the wall12, in which the opening 11 is formed, and upon the relative distancefrom the opposite faces of the wall 12 at which it is desired to disposethe window-hanging frame 66. When the strips 107 to 110 inclusive and114 to 117 inclusive are varied in relative shape and size the bracingstructure 100, when set up, will be effective to cause unification ofthe various elements of the mold 10 upon the frame 66 so as to alter thewidth of wall which the mold will fit as well as determine the distancesfrom the opposite faces of such wall'at which the fra-me 66 will bepositioned when the mold 10 is fitted thereto. y

When the bracing structure members 101, 102 and 103 have been placed, asshown in Fig. 1, the vertical spacers 104 are pried into place to retainthe bracing structure members 102 and 103 in position7 between thebracing members 101, this causing the whole bracing structure 100 to beretained in eX- panded position.

A channel 130 is formed in the lower' edges of the sill portions 95 of amold member 72,

and a channel 132 is formed across the lower edges of the sill portions87 of the mold member 71. Channels 133 are formed on the outer edge ofthe jamb and head portions of the various elements of the mold members71 and 72. When the mold 10 has been assembled upon the window-hangingframe 66, as just described, it is set upon the courses of slabs 61 and62 at the position in which it is desired to form a casing 65, andhigher courses of sla-bs 135'are built upon the the courses 61 and 62 sothat the ends of these higher courses of slabs 135 terminate at the sideedges of the opening 11, as shown at 136 in Figs. 2 and 5. When the mold10 is thusset upon the courses of slabs 61 and 62 an angle iron 138 isplaced in the channels 130 and clamps 140 applied thereto to rigidlyhold the sill portions 95 of the mold 10 against the outer face of theouter facing member 13.

.The clamps 140, as clearly shown in Fig. 7, each comprises a clamp body141 and a bolt 142, the bolt 142 being supplied with a. washer 143 and anut 144. In applying the clamps 140, the bolts 142 are extended througha suitable hole in the'body 141 so that a long foot 145 of the bodyengages the adjacent edges of an adjacent pair of slabs 15, and so thata short foot 146 of the body 141 engages the angle iron 138, and so thatthe bolt 142 eX- tends between the slabs engaged by the foot 145 andreceives the washer`143 and nut 144 upon the inside of the slabs. Whenthe clamps 140 are thus applied to the angle iron 138 andthe bolts 142tightened up, the foot 146 forces the angle iron 138 toward the outerface of the wall facing 13 to effect a clamping of the mold 10 theretoas above described. In a similar manner, an angle iron 150 is disposedin the channels 132 and clamps 140 applied thereto to clamp the sillportions 87 of the mold member 71 against the course of slabs 62.

As the upper courses of slabs 135 are erected the ends 136 of thesecourses project inward va slight' distance within the jamb portions ofthe mold 10 so that the channels 133 of these jamb portions abut againstthe outer faces of the wall facings 13 and 14 along the edge of theopening 11. Angle irons 153 are then disposed in the channels 133 andclamps 140 are applied, as clearly shown in Fig. 1, to rigidly clamp theamb portions of the mold to the outer faces of the facings 13 and 14.The course of slabs 155 which extends across the top of the opening 11projects downward just within the channels 133 formed upon the headportions of the mold 10. An angle iron. 156V is then placed in thechannels 133 of the head portions of the mold 10 and clamps 140 applied,as shown in Fig. 1, whereby the angle iron 156 rigidly secures thechannels 133 of the head portions of the mold 10 to the upper coursesofk slabs 155.

The facings 13 and 14 may be erected entirely about the mold 10, asshown in Fig. 1, before the interior of the wall 12 is poured full ofconcrete above the point 60. This however, is not the usual methodcontemplated for it is desired to pour the silll portion of the mold l10when but one or two courses of slabs 135 are erected upon the courses 6land 62. The advantages of this are obvious inasmuch as the pouring ofthe sill at this time makes it possible to work'the plastic concrete infrom the sides until the sill cavity 160 of the mold 10 is entirelyfilled with plastic concrete. The facings 13 and 14 may then be built uphigher and the farms 48 may be drawn up and repositioned for continuingthe vertical air spaces throughout the height of the wall as previouslyvdescribed. In this manner the wall 12 which is disposed about theopening 1l and the mold 10 is poured full of plastic concrete in such amanner that a casing is formed about the opening 11 which is monolithicin texture with the interior of the Wall 12. This feature of myinvention is most clearly shown in Figs. 2 and 4 in which the integralunion of the wall and the casing is graphically shown.

When the casing 65 has sufliciently set, the structure 100 is dismantledby removing the spacer boards 104, and the clamps 14() are removedV byunscrewing the bolts 142 from the nuts 144 and washers 143 which remaininside the wall, and the various elements of the mold 10 may then bedrawn separately from the casing cast therein, leaving the finishedcasing formed about the wall opening 11, as clearly shown in Fig. 3.

It is of great importance that the method of this invention enables thecastingof a window-hanging frame 66 in the concrete of a monolithiccasing so that there is no pos. sibilit of water entering the housebetween the window-hanging frame 66 and the con-1 crete of the casing.

In constructing those portions of the ele-Y ments of each mold memberwhich telescope together in pairs, it is preferred to bend each .ofthese pairs from two thin sheets of metal, temporarily soldered orotherwise secured together face to face and passed through a form-- ingdie or break as a single sheet of metal.

After thus being bent in the proper shape together, each pair oftelescoping mold-element portions is released from the other and slidapart, and they are then mitered and joined with the other portions oftheir corresponding mold member elements. Each of these pairs of elementportions,` isthen brought together in the assembling of the mold 10 inthe same relation as they had when they were formed. Thus a perfecttelescopic union is made between these various telescoping pairs ofmold-element portions, and the slight break in the surface of thecasing,

formed in the mold 10, due to the joints be-v tween telescopingelements. of the mold, is reducedl to an. absolute minimum.

` If it is desired, any slight irregularities, such as those abovenoted, may be smoothed overafter the mold 10 is removed, by theapplication of a slight amount of plastic concrete. of finishing gradewith smearing templates which are provided with the same conformation asthe inner and outer faces of the head, jamb and sill' portions of thecasing.

The use of the airspace forms 48 is not illustrated in Fig. 1 as thiswas thought unnecessary, but in the fragmentary view of Fig. 2 showingthe portion .of a completed wall with which the easement 65 of myinvention has been integrally cast, vertical Vair spaces 162 are shownwhich have been formed in .the interior concrete 163 of the wall 12 bythe air space forms 48.

In Figs. 13, 14 and 16 I show a modied form of window-hanging frame 170which comprises a rectangularly-shaped woodenV frame 171, upon oppositefaces of which are secured, preferably by means of screws 17 2, angleedging plates 173. The edging plates 17'3 areprovided with perforations174 for a purpose to be described later. A InoldlOa which is similar tothe mold 10 is assembled upon the inside of the window-hanging frame 170in practically the same manner as the mold 10 is assembled'upon theframe 66, with the exception that the middle mold member is dispensedwith in the mold 10a and theinner edges 175 and .176 of outer and `innermold members 71a and 72a thereof are` modified so these modified edgesv17 5 and .176 might lit neatlyV into recesses 177 and 178 formed in theinner face of the opening 179 of the frame 170, l

An inner bracing frame 180 is then applied to rigidly assemble the outerand inner mold members 712L and 72a upon the frame 17'0, as clearlyshown in Figs. 13 and 14. It will clearly be understood that as a resultof dispensing with the intermediate mold' member 70 in the mold 10a, theframe 170 is not adjustable as is the frame 66 to varyits Vrelativedistance from the opposite faces Vof the wall 12.

The reason for providing the frame 170' between the Casement 65 and theframe 170.V

The perforations 174 are for the purpose of receiving cement so that theedging plates 173 will not entirely divide the material of the easementand thereby weaken the structure thereof.

Fig 17 shows a novel cornice 190 which :angle irons 192 and 193 whichrest upon the upper end of boards 195 which are sawed out so as to fitinto the inequalities of the mold 191 and rigidly hold the angle irons192 and 193 thereagainst. The boards 195 are secured to the outer facingmember 13 of member 13, which might be set up opposite the uppermostcourse of slabs 197 of the inner facing member 14, is omitted. When thetop of the wall 12 is poured the cornice 190 is thereby 'formedintegrally with the interior of the wall'.

A gutter 198 may be formed in the upper face of the cornice 190 by theplacing of a tube. 199 in the upper surface of the plastic concrete whenthis is poured into the mold 191, this tube being shown in dotted linesin Fig. 17.

.A tile roof 200 is shown mounted upon the` top of the Wall 12 as in thecompletion of the building in which the wall 12 is a part.
